votes

I want to calculate the variable importance by using weka. I read "Implementation of Breiman’s Random Forest Machine Learning Algorithm" article that it uses tree.RandomForestExt classifier and it has importance variables. I have three version of weka and all of them have tree.RandomForest classifier and this classifier does not has variable importance. How I can download tree.RandomForestExt classifier for my weka tool?

Your best bet is to contact the authors of what you're reading and ask them. – Lars Kotthoff

This link will download you a Custom Weka distribution, made by Fred Livingston, where you could find RandomForest Extension.
